Cool, but I kind of wonder if D&D has grown close enough as it is to being a board game.
For people who want to emphasize storytelling and role-playing, I recommend checking out Burning Wheel:

That's not to say you can't do good collaborative storytelling etc. in d20, but Burning Wheel has explicit structures & rewards for doing so.
